v COMBINATION-RIG FOR DRILLING.

Application filed December 11, 1918. Serial No.

To all whom it may concern: I

Be it known that I, JESSE A. MORRISON, a residing at Mountainair, in the county of Torrance and State of New Mexico, have invented certain new and useful Improvements in Combination-Rigs for Drilling, of which the following is a specificatiomreference' being had I to the accompanying drawings. v

This invention relates to combination rigs thelike, and it is an object and improved device of this-general character whereby the rig may be changed from standard to rotary or vice versa with a minimum of labor and time.

It is also an object of the invention to provide a novel and improved combination rig of this type wherein the rotary or standard are so related as to offer no obstruction one tothe other during its operation.

A further object of the invention is to rovide novel and improved combination rig of this type which does not interfere with spudding or pipe driving or any standard'work, and wherein the calf wheel can be used with .convenience for handling underreamer and other work. An additional object of the invention is to provide a novel and improved combination rig of this gen-.

eral character wherein the band Wheel shaft is operatively connected with the drive shaft of the rotary mechanism so that either the standard or the rotary may be operated by the same motor and which motor may be of any type preferred.

- 'The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved rig whereby certain important advantages are attained and the device ren dered simpler, less expensive and otherwisemore convenient and advantageous for use, as will be hereinafter more, fully set forth.

. The novel features of my invention will hereinafter be definitely claimed.

In order that my invention maybe the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein: I

illustrating a combination rig constructed in accordance with an embodiment of my invention; and

Fig. 2 is a view'in top plan of the structure as shown in Fig. l.

As disclosed in the accompanying drawings, 1 denotes a band Wheel shaft rotatably supported in a conventional manner and which isjprovided at one extremity with acrank 2 with which is adapted to be operatively connected a' pitman' 3 coacting with an end portion of the walking beam 4. Also affixed to the band wheel shaft 1 is a band wheel 4 and the tug pulley 5 as employed in the conventional The shaftL adjacent its opposite extremity has also afiixed thereto the iron tug wheel 6 for the calf' wheel 7 'rotatably supported in a conventional manner by the calf wheel posts 8.

9 denotes the floor of the derrick D and said floor 9 is provided with a rotary table 16 for properly turning the rotary drill tools said table is provided at its llp-' per face with an annular gear or rack 11 with which meshes a gear 12 carried by a suitably supported shaft 14. The shaft 14 has also aiiixed thereto a sprocket15 around which passes a chain 16 also directedaround a drill drive sprocket coactin with the drive shaft 17 of the rotary drilling outfit R, said shaft extending longitudinally the rigging. I

The outfit R is arranged at one side of the derrick' floor 9, mounted upon a derrick mud sill 18 and at a point between the calf wheel 7 and the bullwheel 19.

Bolted as at 20 to the jack post 21 and bolted as at 22 to the su -sill 23 is'an upstanding post 24 and extending upward from certain of the floor sills 23 and the mud sill 18 are the posts 24 in longitudinal alinement with the post 24. Supported by the posts 24 and 24*.is a'line shaft 25 and the end portion thereof adjacent the post 24 is provided with a gear 26 in mesh with a ear 27 mounted uponthe band wheel sha t 1.

The line shaft 25 is substantially in parallel- Patented Jan. 6, 1920.

type of standard rigs. 1

ism with the drive shaft 17 of the rotary drilling outfit hereinbefore referred to. Loosely mounted on the opposlte endportion of the shaft 25v is .a sprocket wheel 28 around which is directed a chain 29 which is also disposed around a sprocket 30 carried by the drive shaft 17 of the outfit R. The sprocket 28 is provided with a clutch face 31 with which engages a clutch member 32 mounted for sliding movement upon the shaft 25 but capable of movement endwise thereof so that the sprocket 28 may be rendered operative or inoperative in accordance with the requirements of practice. a

When it is desired to employ the standard rig the clutch member'32 is disengaged from the clutch face 31 of the gear 28 and when it is desired to employ the rotary outfit R From the foregoing description, it isv thought to be obvious that a rig constructed in accordance with my invention is particularly well adapted'for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof, and for this reason I do not wish to be understood as limitingmyself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

What is claimed is:

A drill rigging of the class described comprising a band wheel shaft adapted to operate a walking beam, a rotary carriage, an outfit coacting with the carriage and positioned at one side of the rigging, including a drive shaft extending longitudina'lly of the rigging, a line shaftdriven by the band wheel shaft, said line .shaft also extending longitudinally of the rigging, an operative connection between the line shaft and the drive shaft .of the outfit, and means for rendering'said last named connection inoperative.

In testimony whereof I hereunto aflix my presence of two witnesses.
